We've seen Google take Maps indoors, with interior schematics and even photos, but the Nexus 7 tablet brings a new twist to that familiar nav experience with 360-degree venue photos. Engineering Director Chris Yerga demonstrated the new feature within a local San Francisco bar called District, moving the device to show us how the compass and gyroscope work to provide 360-degree views based on your current direction and angle -- it's a pretty slick effect. There's also offline map viewing that expands the Google Labs map caching to include entire cities, which should definitely come in handy for navigating beyond your comfort zone (and mobile coverage area). Naturally, there's also an updated YouTube app, letting you take full advantage of that 7-inch display with video preview grids and HD playback, with a familiar Play store-like interface. Stay tuned for a closer look at these apps and more in our Nexus 7 hands-on.
